Hello! You can Call me Sinny. 28. This is my 18+ NSFW Undertail Fontcest & Sanscest blog. I am a fanfic writer & artist. I also reblog art, comics, & audios from artists I support. Feel free to brows around. NOTE: I am more active on other social media after the nsfw purge. You can find me on Twitter: @SinnySkelle | Pillowfort: SinnySkelle
These two are Fell and Swap concepts of Cross I created many years ago.
Just because I donât draw them anymore doesnât mean anyone can take them without letting me know, claiming to be their new owner and getting away with it. Itâs disrespectful and disappointing.
Of course you can still using my concepts for your fan content, or create new ones based on another characters, but credits are necessary. You CANâT STEAL an already existing concept and demand to get all the credit just because itâs an âabandonedâ idea.
Well it looks like yet another platform may be following Tumblrâs example and purging all NFW content and accounts. So I thought this would be a good time to shout out my other socials on where you can find me.Â
NOTE: Iâm no longer active on Tumblr. I am a NSFW content creator so I do not feel welcomed here, and Twitter may be soon. So most of my activity is on Twitter right now, but if it gets purged I will be moving to Pillowfort.Â
Feel free to follow if you want more undertail sanscest, fontcest, and UT Multiverse content.Â

âThis is stupid Dream.â Nightmare leaned against the wall of this universeâs Muffetâs. Across from him, his brother Dream smiled so wide it was nauseating.Â
Nightmare had forgone his corruption for this little event at his brotherâs request. Heâd borrowed clothes from Dream, losing his normal deep purples for the obnoxiously bright yellows to hide his true identity, all for a single purpose that he wasnât sure was good enough. He recalled his earlier conversations with Dream while taking steadying breaths.Â
âYou say that, but you did it anyway.â Dream waggled his eyebrows. âIâm telling you, stop overthinking!â He flicked Nightmareâs forehead with his tongue out.
âHeâs going to be upset we deceived him.â His eyes looked over the masses for the skeleton in question. His unusual height and bright white jacket made him stand out even amongst the diverse crowd. His hands wrung themselves with the unnatural worry that his normal corruption would have shaken off in a heartbeat. Being without it felt like being exposed, its dense protection a reminder of what had changed.
âHeâll get over it. Donât tell me you wanna back outâŚâ Dream teased. He laughed at Nightâs instant glare. âI promise! Itâs gunna be great!â His brother took his hand before he could complain and dragged him into the fray.
Nightmare twitched as his tentacles slipped over his body. He screwed his eyes shut. He almost wished heâd never seen them. Those two little points in Crossâ teeth. Something most Sanses didnât have. Nightmare stared at his desk as he raised a hand to the side of his throat. He didnât want to do paperwork. His ecto was finally summoning and his tentacles sure werenât helping as they rubbed him quietly.
âFuck...â He hissed under his breath. He just had to be patient. Theyâd been doing this all day. He gasped as the tentacle between his legs grinded itself against his clit again. Two other tentacles kept his thighs firmly apart. He sat behind the desk, hunched over it a little. A few more minutes and Cross would be reporting to him with details about the mission.
âCross...â Nightmare echoed his thoughts shakily, tipping his head to the side as a tentacle curled up against his neck. He made another shaking noise. Theyâd been like this all FUCKING day. He couldnât get a single fucking paper done because of it. âFuck...â He whispered softly. There. There!
His tentacles all froze as he could hear the brisk footsteps making their way towards the door. Nightmare shook quietly. He took a deep breath and pushed himself to his feet, his tentacles finally releasing his thighs after hours. He moved around the side of the desk and over to the door. He reached out and swung it open. Cross was shocked, seemingly having been about to knock. âB-Boss! I-â
He yelped in shock as one of Nightmareâs tentacles wrapped around his waist and yanked him inside. He shut and locked the door before throwing Cross against the couch and pinning him down by straddling him. Cross seemed too shocked to speak, staring at him with wide eyes. He sputtered and Nightmare growled, shutting him up.
He reached up and forced his fingers into Crossâ mouth. Cross was taken back before opening it. Nightmare tipped his head again, tracing his fingers along Crossâ fangs. He shivered and let out a shaky exhale. His tentacles began to pull down his own shorts. Cross made a muffled noise of confusion and Nightmare gave a bitter little laugh.
âSurely... surely, Cross, you arenât so shallow to think last time was a one-time thing... Iâm... entrusting you... with my basic sexual needs...â He groaned weakly as his tentacles began to rub between his legs again, making him lean forward, pushing his ass up into the air. It was his female ecto and he made sure his breasts were pushed up against Cross, who was dark purple all the way down to his pelvis, which was starting to glow and grow.
Nightmare trailed his eye down to it and grinned almost sweetly. âFantastic. I knew you wouldnât disappoint me...â He murmured as one of his tentacles gave a wag. âTake it out.â Cross froze up and Nightmare growled. âNOW.â Cross fumbled to pull his cock out of his shorts. It was stiff as a board as it twitched. Nightmare shook as his tentacle grinded against his clit again.
âYou are to blame for my horrendous state. And I expect that you will take full responsibility...â Nightmare growled. Cross clearly had no idea what heâd done, his legs shaking. He nodded anyway, his eyes wide. Nightmare pushed himself closer. He forced the tentacle between his legs out. It clearly didnât like that and began to slick up another entrance, sliding between his ass. âMy hips, Cross. Hold my hips.â He managed to order in a strained voice.
Crossâ hands were felt shakily holding his hips. âY-Yes, Boss.â His own voice was strained as well and it didnât appear to be the only thing that was. Nightmare lined himself up and sank down onto Crossâ cock, making him moan. Nightmare tipped his head back as Crossâ hands tightened on his hips. Nightmare cried out as his tentacle suddenly pushed inside of him from behind. It forced him to lean forward, his arms wrapping around Crossâ neck.
Crossâ breathing was shaky and so was Nightmareâs. Nightmare risked a glance down to see Cross staring at him in worry, along with thick arousal. Nightmare slid his hands out to his shoulders and gripped them. âCross.â It was pleasing how fast his subordinate looked at him and he gave his cock a small squeeze, making Cross shudder. âI want those fangs put to good use.â He murmured, slowly exposing his neck to the other.
Cross inhaled shakily before giving a breathless nod. Nightmare felt his fangs trace along the side of his neck. Nightmareâs hands slid down and gripped Crossâ wrists before pulling his hands up to his chest. âFucking touch me.â He muttered. Cross was shaking as he nodded. He grabbed Nightmareâs breasts and both of them let out a shuddering breath as he squeezed them.
Cross gently bit his shoulder and Nightmare gasped, squeezing on Crossâ cock. His warm breath was felt against Nightmareâs neck and he moaned. Nightmare slowly began to bounce himself up and down on Crossâ lap, making the soldier groan and quiver a little. Nightmare kept Crossâ hands on his breasts, his tentacles beginning to slide down the otherâs arms to keep him there.
Cross gulped and finally pulled Nightmare back down against him, inhaling quietly before gently biting the side of his bossâ neck. Nightmare squeezed down on him again. âYouâre doing good, Cross. Keep it up.â He rumbled. Cross was felt shuddering as he nodded against him.
Nightmare began to slowly bounce himself on Cross once again. He wanted the soldier to snap. In fact, he was counting on it. He inhaled shakily as he felt his own tentacle thrust in his ass in time with his bouncing, jarring him a little and making him moan. Crossâ hands tightened on his breasts. Nightmare looked down at him.
Cross was purple to his shoulders and breathing odd. âCome on.â Nightmare chuckled softly. He was still moving slowly and Cross made a weak noise. âFrustrated?â Nightmare asked quietly, tipping his head innocently. Cross twitched and finally seemed to break.
He surged forward, turning and slamming Nightmare against the couch. Nightmare let out a breathy laugh before moaning, the sound bordering on a shriek as Cross began to fuck into him mercilessly, his hands obsessively rolling Nightmareâs breasts. âFUCK.â Cross growled out.
Nightmare felt proud before pleasure overwhelmed him and he held onto Cross desperately. He couldnât handle it for very long. His tentacle was still thrusting in him from behind and Crossâ loud, breathy moans told Nightmare the other could feel it rubbing up against his cock. Nightmare wrapped a tentacle around Crossâ waist, yanking him closer.
The motion made both of them groan and Nightmare arched his back, spreading his legs a little wider and giving Cross a flushed grin. âThere... there we go...â He purred. Cross inhaled sharply and leaned down, forcibly pressing their teeth together. Nightmare was momentarily shocked.
He paused, his arms up. He finally slipped them up around Crossâ neck, pressing back against him. He moaned shakily. If this was how Cross would react to provocation, he couldnât wait for their future arrangements.
Dream stared at the empty vial that Ink had set on the desk separating them. âI-Iâm... Iâm not sure I understand...â The prince set down his pen, raising a brow at the artist. Ink sighed. He picked up the vial, holding it between his fingers. âThere... there was no yellow?â
âThere was no yellow.â Ink confirmed with a quiet nod. âEvery other damn color was there when I went to refill. But not yellow. Yellow is my happiness vial. And itâs empty.â He laid it out clearly for Dream. Dream was taken back and he looked down.
âIâm sorry, but I... I donât understand why you would come to me...? I canât get the... Creators... to give you a shade of paint. And I donât have any...â Dream paused as Ink shook his head.
âListen, Dream. Youâre my best friend, right?â Dream blinked before nodding and telling him that he was. âAnd friends help each other so they donât become emotionless husks, right?â Dream paused before furrowing his brow and nodding. âWell, Iâve found a way to replace my paint, but Iâm going to need your help and Iâm gonna need you to trust me.â Trust him? Dream faltered again.
He was Inkâs best friend. But Ink was... problematic... to say the least. There was something about a monster without a soul asking Dream to trust him that rubbed him the wrong way. He looked away before sighing. âOkay... how can I help?â He asked, turning back to face him. Ink stared evenly at him and spoke.
âI need to use your soul.â Dream choked for a moment and shook his head. He began to sputter and Ink cut him off. âDream. If I donât have that color, I donât have a full set of emotions and Iâm GOING to become unstable.â He rolled his eyes. âMy intent is not to kill you. Itâs really not that big a deal.â Dream stared at him. Except it kinda was.
To trust someone with your soul was quite a big deal and Dream figured that because Ink didnât have one, he didnât understand that. He gulped and opened his mouth to speak before Ink met his gaze. âYouâre really not going to help me?â Ink sounded disappointed and taken back. His voice had become an emotionless, monotone drawl. Dream faltered. âYou say youâre my best friend, and youâre not even going to help me.â
âI want to, b-but giving you m-my soul is...â He trailed off, not sure how to put it without upsetting Ink, who stared at him.
âYou donât trust me. Weâre supposedly best friends and you donât trust me. Even though I trusted you with my secret about my paints.â Ink sounded betrayed and Dream panicked a little, not wanting Ink to be upset.
âIâll do it!â Ink blinked at him. Dream sighed and looked away, rubbing his arm. âIâll... give you my soul and you can do whatever you need to with it...â He felt awful. Ink seemed to notice and shook his head, turning away.
âIâm not going to make you do it.â Ink muttered. âIâm not that kind of monster.â He turned away and Dream stood up, using his magic to shut and lock the office door, startling Ink into looking back at him.
âNo! I said Iâm going to help! So let me help!!â Dream said firmly. Ink stared at him with an unreadable expression before sighing. He nodded and muttered fine. He moved back and went over to the couch. Dream summoned his golden apple soul and Ink called it over to him, holding it in his hands. âDo you want me over there?â
âNo, you can keep working on paperwork.â Ink said dismissively, his fingers beginning to ghost over the surface. Dream blushed and nodded, picking up his pen. He was in the middle of signing something when Ink gave his soul a rough squeeze and he yelped, covering his mouth. He looked over at Ink, who just seemed focused on the task in hand.
He wet one of his fingers before beginning to push it inside the soul, causing Dreamâs body to jerk and he slammed his foot into the desk, leaning over and laying his head against it. He trembled, his eyes wide. Was Ink even aware of what he was doing?? There was a burning heat along Dreamâs bones. It only got worse as Ink wet another finger, adding it to the one already inside, stretching open Dreamâs soul.
His body gave a violent shudder and his ecto was beginning to form as a way to relieve some of the heat. He gasped as his leggings began to tear, the fake, golden flesh poking through. He made his first actual noise, moaning as Ink pushed his tongue inside his soul. He began to circle his tongue around, making Dream twitch and his newly formed cunt throb. He continued to lean against the desk, trembling against his papers as he rubbed his legs together.
He heard a popping noise and looked up. His eyes widened and he cried out in shock as Ink began to push the open end of the vial into the opening in his soul. He cried out, shaking and Ink glanced at him. âI canât afford to lose any of it.â He murmured. Dream twitched and his body was burning as he sat in his chair. He let out a weak, shuddering noise as Ink got up. His leggings had torn along his entrance and he shook, knowing his cunt was already slicking up.
Ink moved behind him and reached down, the soul floating next to him as he grabbed Dreamâs hips and pulled him up so he was bent over the desk. His legs shook and he asked Ink weakly what he was doing. âI need to speed up the process, Dream. That way, itâs less awkward for the both of us.â Funny. Ink didnât sound embarrassed at all. Dream, however, was a shaking, blushing mess, bent over his own desk in front of his best friend.
Ink lifted the back end of his coat and blinked. âWoah, your leggings are completely shredded. I can see everything...â He began to slip his fingers into the rips, making Dreamâs breath catch in his throat as he whimpered. He was in his female form, his breasts pressed uncomfortably against the hard surface of the desk. Inkâs hands began to wander over to his folds and he tore what little fabric was hiding it, fully exposing Dream.
The guardian felt humiliated and shook under Inkâs touch, trying not to just burst into tears. He yelped, his legs slamming against the desk against as Inkâs finger suddenly pushed past his folds and straight into his entrance. âMaybe I shouldâve stuck the vial in here...â He began to move his fingers around inside of Dream, making him jolt in shock. Ink paused. âOkay, itâs getting a little wet...â
Dream was on the verge of tears and he hiccuped. Ink sighed. âThis is no good like this.â He felt Ink pull back, leaving him trembling and exposed. There was a pop and Ink inhaled quietly. Dream yelped as he was grabbed and turned, being laid back against the desk. He sputtered, staring up at Ink with wide, teary eyes.
He blinked as the other opened his jaws, revealing a glowing, bright pink liquid and leaned forward. He connected their mouths and Dream screwed his eyes shut, trying to pull away. Kissing?? He hadnât been told about any of this!! Ink held him there, fingers pressed into his jaw. Dream opened his mouth to protest and yelped as he felt something be pushed into his mouth.
Inkâs tongue was accompanied by a strange sort of cream. It tasted like vanilla and strawberries. He didnât want to swallow it, but he felt Inkâs fingers around his throat, pressing a spot that caused him to choke a little and the substance was pulled down his throat.
Ink sighed and leaned back, a bit of the glowing liquid dripping down his chin as he licked it up. His eyes were calm. Dream gulped, trembling against the desk. âWh-what did you j-just give me?â He whispered. To his horror, Ink only responded with a soft grin as he tucked what was left of the bright pink vial back into his throat. He shuddered.
His body felt strange and he shivered, suddenly curling in. He felt restless. He squirmed, his bones growing hot. âOh...â He groaned, his face heating up. Ink slowly turned him back on his stomach against the desk. He spread Dreamâs legs a little and began to explore inside of him again, making him shake as pleasure burned through him.
His thighs twitched and he found himself pushing his hips back against Ink, wanting more. âInk! Ink, please...!â He was so hot and he tried to cling to the desk, tearing some of his papers. He hiccuped as Inkâs exploring got deeper and deeper. Inkâs fingers stopped and Dream whined as he pulled them out. His cunt kept squeezing down on nothing and heâd never been more aware of the intrusion in his soul.
Something thick and hard rubbed against his folds from behind after a brief period of shuffling. Dream froze up, his eyes wide as tears ran down his face. âW-Wait... wait, Ink- INK!!â He shrieked as he felt Ink enter him, slamming him back down against the desk. It hurt. He began to cry weakly. Ink paused, gripping his hips. He seemed taken back.
âAre you...?â He snorted and rolled his eyes. âWell, WERE you a virgin, Dream?â Dream began to cry louder and Ink sighed. He waited for a moment before slowly beginning to thrust. Dream gasped and moaned, holding onto his desk as his body was rocked. The pain was fading and burning pleasure was starting to replace it as Dream tried to open his legs wider.
He screamed out as Ink slipped in deeper and his hands curled into fists. His soul was pounding and dripping. He could see the vial beginning to fill. He was growing close and Ink continued to pound into him even harder, causing the desk to scoot across the floor. Dream tightened hard as he wailed Inkâs name. He came with a jolt, his cum spattering the desk as the vial was seen filling up with golden liquid.
Ink didnât stop and Dream cried out, his face completely tearstained as he felt Ink release inside of him. He groaned, feeling it in his belly. There was a lot. He felt Ink pull out, leaving his cunt throbbing and burning as cum trickled out and began to spill down his legs. Ink hummed, dissipating his ecto as he reached up and began to pull the vial out of Dreamâs soul, causing him to tearfully moan again.
It left him with a wet pop and his body twitched. His soul was shaking as it returned to him. Ink closed the vial and grinned at Dream, who was still bent over the desk, trembling. âI donât think I have enough words to thank you! You really are the best, Dream!â He knelt down and forced Dream to look at him. âI hope I can rely on you if this happens again?â He sounded hopeful but there was something far more sinister in his tone and Dream shook.
Tears welled in his eyes again as he nodded and Ink smiled. âThank you so much!!â He giggled. He gently pat Dreamâs cheek and stood up, turning away before opening a portal with his paintbrush. âSee you later!â He disappeared through it and it closed, leaving Dream wrecked and alone. He began to cry softly.
Its been awhile since we received a life update from you, are you okay? I know jobs and finances can be stressful, but I just want to remind you that you're awesome and everything is going to work out. â¤
Aww thank you for the concern. âĽÂ
Updates are I am currently unemployed due to covid-19. Silver lining is I was able to work enough before getting layed off to pay off all our debts. We are currently in a stable position even without my income. Unemployment will help that too.Â
Overall Iâm doing great. Taking the extra free time to work on me and my health. As well as getting back into my hobbies like writing and drawing, on top of new hobbies like gardening. I also recently ordered a new laptop so I can draw and write in other rooms while others use the office for work.Â
I know things are kind of a shit show right now for everyone, but they are looking up for me.Â
Thanks for checking in on me ^-^ Sorry if this was hella late response. I rarely come on Tumblr anymore after they killed all NSFW stuff. If you ever want to reach me, you can find me on twitter. Same name c:
This is the best explanation I could come up with for why it takes me so long to do updates sometimes when, at other times, Iâm typing them up like clockwork.
Oh my goodness this is absolutely gorgeous!!! O.OâĽÂ
You did such an amazing job on this. Thereâs detail in every building!Â
Thank you for sharing your beautiful art ⼠Itâs incredible! ^-^
Oh jak to kocham! This is fanart for a certain someoneâs UnderTale fanfic. Talking about you @sinnyskelle , you and your beautiful words.Â
To Love Again: https://sinnyskelle.tumblr.com/To%20Love%20Again
And they have the same username for AO3 so you can find it there too.
Thereâs a scene in Chapter 8, where Red wakes up and is just standing in front of a beautiful cityscape in an upscale condo and Iâve always wanted to draw it, but the task of draw the city was so very daunting. I do hope you guys really like it because I worked really hard on it.
Please enjoy!
June 1, 2019
I wanted to post a little update here because Iâve been getting a lot of repeating asks about fics and when theyâll be updated, or if Iâve abandoned any of them.Â
Short answer is: No I havenât abandoned any fics, and I donât know when Iâll be able to get updates out.
I recently got a job and the work is great, itâs just got really demanding hours. Itâs one of those jobs that end up following you home after hours leaving absolutely no time for me to write, or game, or hell even decompress most days.
I know this job isnât good for work/home life stability, but until my finances are in order, Iâm not leaving it.Â
I try to work on writing on the weekends but itâs been slow progress.Â
Iâm sorry for the wait. I feel the muse, I want to put chapters out, itâs just finding the time to write thatâs holding me back. I appreciate those of you who gave me encouraging words telling me to take my time. Youâre the best âĽÂ
Thank you everyone for your patience! ^-^
